[0024] The following is a clear and complete description of the present application in conjunction with the accompanying drawings. A person of ordinary skill in the art will be able to implement the present application based on these descriptions. Before describing the present application in conjunction with the accompanying drawings, it should be noted that:

[0025] The technical solutions and technical features provided in each section, including the following description, may be combined with each other unless they conflict. In addition, where possible, these technical solutions, technical features, and related combinations may be assigned specific technical themes and protected by relevant patents.

[0026] The embodiments of the present application involved in the following description are generally only a part of the embodiments rather than all the embodiments. Based on these embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative work should fall within the scope of patent protection.

[0027] Regarding terms and units in this specification: The terms "including," "having," and any variations thereof in this specification, the corresponding claims, and related parts are intended to cover non-exclusive inclusions. In addition, other relevant terms are subject to reasonable interpretation based on the relevant content provided in this specification.

[0028] like Figure 1-Figure 5 As shown, an air cooler fan motor bracket comprises a core 11 and at least two connecting arms 12 circumferentially spaced around the core 11. The outer end of each connecting arm 12 of the at least two connecting arms 12 is used to connect to the guide tube 2 of the air cooler. The core 11 is used to carry the motor 3 of the air cooler fan. The blade part of the fan is located in the guide tube 2. The output shaft of the motor passes downward through the core 11 and connects to the blade part. Some or all of the connecting arms 12 of the at least two connecting arms 12 adopt a new design of air cooler. The fan motor bracket connecting arm is an integral part having a first plate-shaped portion 121, and a second plate-shaped portion 122 and a third plate-shaped portion 123 formed by bending at one end of the first plate-shaped portion 121. The first plate-shaped portion 121 and the second plate-shaped portion 122 are connected by a first bent edge 124, and the second plate-shaped portion 122 and the third plate-shaped portion 123 are connected by a second bent edge 125. The first bent edge 124 and the second bent edge 125 are distributed on two adjacent side edges of the second plate-shaped portion 122. The third plate-shaped portion 123 is fixed to the guide tube 2 via a connector.

[0029] The third plate-shaped portion 123 can serve as the exterior of the curved connector (angle steel plate) in the prior application, and the second plate-shaped portion 122 can serve as the interior of the curved connector in the prior application, thereby avoiding the need for the angle steel plate in the prior application to be manufactured separately and assembled with the connecting arm body, simplifying the manufacturing process and improving the production efficiency of the bracket. At the same time, the integrated parts also enhance the structural strength and reliability of the connecting arm.

[0030] In this embodiment, the one-piece part is processed on an L-shaped slab 4, which is divided into a long plate portion 41 and a short plate portion 42; the first plate-shaped portion 121 is formed by the long plate portion 41, the second plate-shaped portion 122 is formed by the corner portion 43 between the long plate portion 41 and the short plate portion 42, and the third plate-shaped portion 123 is formed by the short plate portion 42.

[0031] More specifically, the two sides of the short plate portion 42 are parallel to each other and have an inclination angle of 105°-135° between the longitudinal direction of the long plate portion 41. This feature is reflected in the formed connecting arm 12, where the side 122a of the second plate-shaped portion 122 formed by the corner portion 43, which is opposite to the second bent edge 125, is a bevel corresponding to the inclination angle. In other words, Figure 1-Figure 2 From a middle perspective, the bottom of the second plate-shaped portion 122 is a beveled edge.

[0032] Here, the reason why the two sides of the short plate portion 42 are arranged parallel to each other and have an inclination angle of 105°-135° with the length direction of the long plate portion 41 is to make the arrangement of these L-shaped slabs on the plate more compact when cutting multiple L-shaped slabs from a plate. Specifically, Figure 4 As shown, the inclined arrangement of the short plate portion 42 allows the cutting profiles of the different L-shaped slabs to almost overlap.

[0033] In this embodiment, it is preferred that both sides of the short plate portion 42 are parallel to each other and have an inclination angle of 120°±5° with the length direction of the long plate portion 41 .

[0034] like Figure 5 As shown, the dotted areas represent the first bending edge 124 and the second bending edge 125 respectively. Figure 5 As shown, the first bent edge 124 is parallel to both sides of the short plate portion, and the second bent edge 125 is perpendicular to the first bent edge 124. This feature is reflected in the formed connecting arm 12, that is, the third plate-shaped portion 123 is substantially parallel to the first plate-shaped portion 121.

[0035] In addition, the third plate-shaped portion 123 is provided with a through hole (for being fixed to the guide tube 2 via bolts). A limiting groove (for cooperating with the core 11 for positioning) is provided on the other end of the first plate-shaped portion 121, which is bent relative to form the second plate-shaped portion 122 and the third plate-shaped portion 123.

[0036] like Figure 3As shown, the air cooler includes: a fan, including a motor 3 and a blade part connected to the output shaft of the motor; a heat exchanger, which cools the hot fluid running in the heat exchanger through the airflow generated by the fan; an upper shell, which forms a guide tube 2 and is used to install the blade part; a lower shell, which forms a guide cover and is used to install the heat exchanger; wherein the upper shell and the lower shell are connected to each other; the upper shell is provided with an upper shell material local reinforcement structure, and the upper shell material local reinforcement structure is installed with a bracket 1 for loading the motor, and the upper shell material local reinforcement structure makes the bracket 1 completely supported by the upper shell; the upper shell material local reinforcement structure includes a plastic deformation local reinforcement area formed by plastic deformation of the cylinder body of the head of the guide tube 2, and the plastic deformation local reinforcement area is formed by bending the cylinder body of the head of the guide tube outward; the bracket 1 adopts the above-mentioned air cooler fan motor bracket.

[0037] The applicant has already described the above air cooler in detail in the prior application, and such descriptions may be incorporated into this specification and will not be repeated here.

[0038] By designing the connecting arm as an integral part, the integral part has a first plate-shaped portion and a second plate-shaped portion and a third plate-shaped portion respectively formed by bending at one end of the first plate-shaped portion, the first plate-shaped portion and the second plate-shaped portion are connected by a first bending edge, and the second plate-shaped portion and the third plate-shaped portion are connected by a second bending edge, and the first bending edge and the second bending edge are distributed on two adjacent side edges of the second plate-shaped portion. In this way, the third plate-shaped portion can be used as the outside of the curved connecting piece (angle steel plate) in the prior application, and the second plate-shaped portion can be used as the inside of the curved connecting piece in the prior application, avoiding the process of separately manufacturing the angle steel plate and assembling it with the connecting arm body in the prior application, simplifying the manufacturing process, and improving the production efficiency of the bracket. At the same time, the integral part also improves the structural strength and reliability of the connecting arm.

[0039] The above describes the relevant contents of this application. Based on these descriptions, a person of ordinary skill in the art will be able to implement this application. Based on the above contents of this specification, all other embodiments obtained by a person of ordinary skill in the art without making any creative efforts should fall within the scope of patent protection.
